NAME
Mixin::Event::Dispatch::Bus - a message busVERSION
version 2.000SYNOPSIS
{
package Some::Class;
sub bus { shift->{bus} ||= Mixin::Event::Dispatch::Bus->new }
}
my $obj = bless {}, 'Some::Class';
$obj->bus->subscribe_to_event(
something => sub { my ($ev) = @_; warn "something!" }
);
$obj->bus->invoke_event('something');
DESCRIPTION
This class uses Mixin::Event::Dispatch to provide a message bus - instantiate this and call the usual methods to deal with events:- "subscribe_to_event" in Mixin::Event::Dispatch
- "invoke_event" in Mixin::Event::Dispatch
This allows several classes to share a common message bus, or to avoid polluting a class with event-related methods.
